, y 30. Whilemy' invention is not limited particularly to a lockemployed for any` speciiic purpose,yet, as it is particularly adaptedfor controlling the lock mechanism oi' doors-for closing compart mentsprovided iorpublic use, :such as toilets and u' the like, I haveillustrated and described my invention herein lin connection VWith sucha lock. In theV drawings'herein the numeral I-5 denotes a portion of thedoor frame o1' jamb of a door opening, as to a toilet compartment, andI6 denotes 1 a portion of the Ydoor that closes such opening.

A keeper plate I1 is secured .to the jamb-infany suitable manner andaiords a support for a keeper I8 having an opening to receive a boss i9projecting from 'the frontedge ofa lock case 45 2t, said keeper alsohaving a keeperrecess 2i V`to receive rthe outer end of alatoh bolt 22mounted for reciprocating movement Within the case.V The case 29 isaffixed to the front ofthe door I6 and has a back'plate 23. securedthereto in any suit-v 50 able manner for closing the chamber thereinanda coin slotl 24 in the front of the case opens'into the interiortherein. A guiding lug'23 projects .from the inner face of the front ofthe case and has a ledge 26 as shown in Fig. 22 forming a track 5 5 fortravel of a coin or token into a dish-shaped coin receiver 21 supportedat the end of a coin receiver arm 28 rotatably mounted as hereinafterexplained. A knob spindle 29 is rotatably supported at one end in abracket 30 extending across the case intermediate its front and backWalls, a leg 3l of the bracket being secured to a post 32 projectingfrom the front wall of the case for the support of one end of thebracket and its opposite end 33 being secured within a recess 34 in theboss i9, as shown in Fig. 4 and in dotted lines in Fig. 9.

A connector comprising a sleeve 35 and a head Y55 `onvthe latch.bolt.22.--having been engaged, by the vuse of a key, with -the notch 39, thisbeing the normal and coin 36 is rotatably mounted in and. extendsvthrough the front wall of the case.as shown in Figs. .14

and 1'7, the knob spindle 29 being supported in this connector. A recessintheconnector head 36, encloses a spindle head 31 on the spindle-29,said spindle head carrying a locking bolt 38 having one end movable intoaY locking recess 39 on the inner wall of the connector head 36, asshown in Figs. Y 14 and 1'6. rIfl'ie bolt 38 isengaged by aneccentrically mounted pin I4 on the end of a plug 40 of a pin tumblerlock which plug is mounted in the shank of an entrance knob 4I. 'I'hispin tumbler lock is of old and well known construction and afurtherand'detailed description is therefore omitted herein. A spring presseddetent 42 inthe spindle -head 31 engages notches in the locking bolt'38to yieldin'gly retain said bolty in locking or unlocking positions, thedetent' yielding, when pressure is applied to the bolt, to enable it tobe moved. vThe shank or hub of the knob 4| is secured to the spindlehead 31 by means of a screwV I3 as shown in Fig. 15.

The locking mechanism just described is to enable the door bearing thelock case 20 to be opened without the use of La coin. To effect thispurpose a key, usuallyin'the possession of an l. attendant'7 is insertedthrough thev opening in the end of the knobl 4| and into the key slot inthe plug 40, said key positioningthe pin tumblers so that the plug 40may be turned. This will operate the bolt 38 to remove its end from therecess 39 in the 4connector head 36 as shown in Figs. 14 and 16. The keynow being turned further, or theknob ifdesired, 4the spindle 29 isrotated within butv independently of the connector 35-36thisbeing'r'effected by reason of the screw I3 (see Fig. 15) which securesthe knob shank to the spindle head y31. This operation of the spindlecauses a pin 43 projecting from the spindle into a groove 44km the wallof a hole in the hub of a dog 45 to engage a shoulder 46 near the rearend ofthe latch bolt 22,y all as shown in Fig; 10 of the drawings.Continued turning movement ofthe key or knobv effects disengagement ofthe latch Vbolt from the keeper and permits the door to be opened.

The coin receiver 21 hereinbefore referred to has a shoulderformingaftrack 41 upon which the coin travels from'the track or ledge 26 untilthe coin islocated within the receiver. A slot 48V isi-formed at oneedge ofthe receiver, extending preferably to` yabout the center thereof.A shelf 49. on the arm 28 constitutes a slide for coins from thereceiver into a coin box 50 1o-A Ycated underneath theouter end oftheslide. A latch bolt actuator is pivotally mounted upon the spindle Y29,this actuator comprising a hub 5| through which said spindle extends, anactuating finger 52 extending from the hub for movement into thecoinreceiver 21, this finger being adaptedftorengage the bottom of thereceiver when not restricted. An actuating d'etent 53 projecting fromone side of the hub 5| is positioned to engage the shoulder 46hereinbefore referred to on the latch bolt22.

In the operation of that part of the structure just described the outerend of the actuating finger 52 will be in a position adjacent to theedge or rim of the coin receiver 21, but spaced therefrom a distance toadmit a coin between the two, the linger being held in this position 'bythe pressure of one end of a double acting -spring 54 wound around thepost 32, and as shown'inFig. 7 of the drawings, the finger in thisposition resting against a coin releasing lug The locking bolt 38operating position of the parts, a coin 56 is inf serted inthe coin slotin the case and rolls along the tracks '26 and 41 into the center of thereceiver 21 where it is nested between the receiver and theend'of theactuating finger 52, and as shown in Fig. 13 of the drawings. 'I'he knob4| now being turned, rotation is communicated to the connector sleeve 35which isy keyed to the coin receiver arm 28, as shown in dotted lines inFig. 14 of' the drawings. Thisrotates the coin receiver`21 and itssupport 35 andmoves the coin in the receiver against the end of thefinger 52 and the latter is vrotated on its axis, carrying the detent53T against theshoulder 46 on the latch bolt and moving the lattertodisengage it from its keeper and permit the vdoor to be opened, theparts now being in the position shown in Fig. 6 of' the'drawings.

However, before the' receiver 21 can bev moved, as justdescribed, areceiver stop 51 at one end of a pivotallyfmounted stop lever 58 must bemoved from the Vpath of the receiver 21. This is effected by engagementof the curved outer side of the finger 52-with a cam`59 on the lever 58,as shown in` Fig., 6 of the drawings. The lever 58 is biasedlagainst thefinger 52 by one arm of the double acting spring 54, all as shown inFig. 6 of the drawings'. With the parts intheir normal positions justprevious to the insertion of a coin movementof the receiver is blockedby the stop -511in its path but' a slight space occurs between a coin inthe receiver 21 and the stop 51 such that after insertion of the cointhe receiver maybe' moved sufciently to enable the cam 59 to ""thro'w'the stop '51 Vout of its path as above described. The object of the stop51 is to compel insertion of a'coinv to operate the lock and to therebyprevent movement of the receiver without the use of a coin, and as bymeans of an instrument thrust through 'the' coin slot or by turningtherknob 4|. After the knob 4| has been turned sufficiently toldisengagethe latch bolt from its keeper to enable the door to be opened, thegrasp of the hand upon said knobbeing released, the receiver 21'isreturned to the position shown in Fig. 7 under the action of a receiverspring 69 aided by' thespring 54 Yacting on the finger 52 and throughthe coin which is Vstillin place in the receiver. In ,this movementthenger 52 acting against i the coin releasing lug 55 moves the latchbolt 6 to 9. A stop lug 64 projects from one edge of the carrier 62 toengage the side of the case and thereby determine the active position ofthe stop as sho-wn in Fig. 6. In this position the outer convex surfaceof the receiver 21,' or a lug thereon', contacts with the stop 6I andpositions the receiver to obstruct the entrance of a coin into the coinslot as hereinbefore mentioned. A spring 65 is secured at one end to apin projecting from the carrier 62 and at its opposite end to a lugprojecting from the wall of the case, the spring being so arranged thatas said carrier is swung in opposite directions the spring will passacross the pivot S3 and snap the carrier 62 into one of its oppositepositions, depending upon which side of the pivot 63 the spring extends,and in a manner that will be readily understood.

The carrier 62 is operated by an actuating lever 56 pivotally mountedintermediate its ends within the case and having a pin projecting fromone end into a slot 61 in the stop carrier 62, the opposite end of thelever being adapted to enter a notch E8 cut into the receiver 2'! in theopposite side thereof from the slot 48, as shown in Fig. 12 of thedrawings. In its normal position of rest the stop carrier S2 is locatedoverlying the receiver, as shown in Figure 9. When, however, the knob Mis turned to operate the latch bolt 22 and release it from its keeper toenable the door to be opened, as hereinbefore described, the coinlocated in the receiver 2l closes the notch 68 in said receiver and thecoin near its edge engaging the end of the lever SS located in the pathof movement of the coin will operate said lever andk swing it into theposition shown in Figs. 6 to 8. This places the back stop El in positionto engage the receiver 2l and retain it in the position shown in Figs.'l and 8.

When the door is closed, following the operations just set out, thelatchbolt 22 engaging with the edge of the keeper, is thrust ba'ckwardlyinto the position shown in Fig. 8. In this movement the coin releasinglug 55 on the bolt engages the actuating finger 52 and swings itbackwardly, thereby releasing the coin 56 which. drops and slides alongthe shelf 49 and olf its edge into the coin box 5e. When the door isfully closed and the latch bolt 22 is in position for movement to engageits keeper the finger 52 will be swung forward under the iniiuence ofthe spring till and engaging the lug 55 on the bolt will move the latterand seat it in the keeper recess, as hereinbei'ore described, the end ofthe nger 52 now extending slightly into the receiver 2l.

A paid entrance having been gained to "tht compartment guarded by thelock and the door being closed and locked as just described, inrusionwill be prevented for the reason that the L sin receiver 2'! beinglocated in front of the coin slot in the case a coin cannot be insertedand it will therefore be impossible to gain entrance'to` the compartmentby the use of a coin. In order to open the door an exit lmob 69 isprovided on the inside of the door, this knob having a spindle. 'leextending through the door and into the lock case. A clog il projectsfrom the spindle into a notchl2 in the bolt 22 near its outer end forengagement with a shoulder l2 at one end of the notch. The knob beingturned the dog engaging the shoulder of the notch retracts the latchbolt and releases it from its keeper so that the door may be opened.This backward movement of the latch bolt Ywill incidentally operate someof the mechanism hereinbefore described, but to no avail. A resetting I5nnger 1S for resetting the back stopmechanism forthe receiver projectsfrom the hub of the. dog 'Il into positionfor engagement with aresetting pin 'M projecting from the back stop 6|, and as shown in Fig.17 of` the drawings. As the knob 68 is turned to release the latch boltthe finger 13 presses the pin 'M backward causing movement of thebackstop 6I from behind the coin receiver 2l andinto a position of restas shown in Fig. 9. Now, as the door is closed, the keeper being engagedby the beveled end of the latch bolt will force said .bolt 22 with itslug 55 backwardly, as' before described, moving the finger 52 againsttension fof its spring, and when the latch bolt reaches a positionto'register with the receiver the spring acting upon the finger 52 willforce said ringer against-,the lug 55 on the bolt thereby moving thelatter into its locking position. In the final Vposition of the parts alug 'l5 on the arm 28 will be forced `by the action of the spring 60against a stop 'I6 projecting from the inner wall of the case, thereceiver being thus located in its position of rest just out of linewith the coin slot 24 and the finger 52 resting against the lug.55 onthe latch bolt will provide a space just sufficient for the entry of acoin between the receiver and said inger.

When the receiver is in its position of rest the stop 5l is locatedopposite the' edge of the receiver just at one side of the notch 68,thus dog-` ging movement of the receiver from this position. After,however, the door has been opened and the coin has. been released thereceiver occupies a position a slight distance forward of that justdescribed. To dog the movement of the receiver forwardly from thisposition a stop 'l1 in the forni of a shoulder at the end of the lever58 is provided andthis will prevent forward movement of the receiverfrom the position shown in Fig. 7. l

To guard against a sticking of the coin within the receiver 2l anejector 18 in the form of a prong extending from one side ofthe latchbolt, i

as shown in Fig. l0, is employed. Should the coin fail to drop from thereceiver upon backward.

movement of the latch bolt 22 in the closing movement of the door, ashereinbefore described, the parts will return to the position shown inFig. 7. This, however, will be ineilective to prevent repeatedfunctioning of the device. Therefore the ejector 'i8 is provided andwhen the knob 69 is operated to release the latch bolt the ybackwardmovement of the latter will engagethe ngerv with the coin and force itfrom the V`receiver.

j It will be noted that there are four stops to 'position the coinreceiver, the stop 'I6 to prevent backward mo-vement by the spring t@from its normalposition of rest,the back stop 6l to determine itsposition during a cycle of operations of the lock, the front stop 5l toprevent forward movement of saidreceiver from its position of rest, andthe front stop 'll to prevent its forward movement after a cycle ofoperations has vcommenced.

In orderjto determine the'number of times lthe door isopened 'by the useof a rcoin a register 7S is employed locatedl at the top of the casingand observable through a window 8i) inthe side wall cated thereon, thedisks-being operatively connected in afmanner well understood and forwhich reason, av detailed description isomitted herein, it

being sufcient to state that the disks `are operated as by means of ashaft 8l extending through one end of the register case that issupported upon a post 82 comprising a part of and rising fromthe-bracket 30, as shown in Fig. 9 of the drawings. A register operatingarm 83 is secured at 'one end to the shaft 8| `and. is pivotallyconnected at its opposite end with a register operating link 84, saidlink being pivotally attached to one end of the actuating lever 66, asshown in Fig. 9 of the drawings.

From this description it will be seen that each time the lever 66 isoperated byforward movement of the receiver 2l with a coin therein, intheoperation of opening the door, the register 19 will bev operated todenote such movement of parts.

In order to aid the movement of the coins from the shelf 49 into thecoin box the latch bolt 22 is cut away on one side forming a downwardlyinclined chute 85, see Fig. 9, along which the coins pass in theirmovement from said shelf.

The coin boX is inserted through an opening in the bottom of the caseand is held in place by means of a locking bolt 8B operated in anyordinary manner by mechanism within the lock case 81 as by means of akey inserted through an'escutcheon 88A in the front of the case 20 in amanner that will be readily understood.

. A bolt stop 39 is formed on the bracket 30 in the path of movement ofthe dog 45 secured to the spindle 29, as shown in Fig. 10. This dogengaging the shoulder @6 on the latch bolt limits its movement under theinfluence of the spring 54 when said dog strikes the bolt stop 89.

In the event that a slug or washer with a hole through the center isattempted to be employed, which devices may be readily obtained, theaction is illustrated in Figs. 20 and 21 in which it will be noted thatwhen the slug passes into the receiver it will momentarily be hung uponthe end of the finger 52, and this being curved to the proper degree,the slug will immediately pass off from the end of the iinger anddownwardly along the shelf 49 into the coin box under the actionl ofgravity. l

The latch bolt 22 has a stop 90 adapted to engage the edge of an opening30 through the bracket 3Q hereinbefore described, in the form as hereinshown-this stop being located at the rear end of a rib 9i the forwardend of which rib constitutes the shoulder 46. The stop limits rearwardmovement of the latch bolt and the stop 89 limits its forward movement.

. In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent the best embodiment thereof;but I desire to have it understood that the device shown is onlyillustrative and that the invention may be carried out by other meansand applied to uses other than those above set out.
